Hi all

I have had my new fish in the new tank for 4 weeks now and my black mollie has whitespot, had him for 2 weeks. I have 5 tetras also, they seem fine. My tank is a 60L and I have just added salt 1tsp to every 4L, upped the temperature. Will do a water change tonight as well. I just want to know how often do I do this, every day, every second day etc.

With using salt for whitespot treatment you only replace what you take out with the water changes as the salt doesn't break down like most medications. Keep the treatment up for a week with tropical fish

1tsp per 4l sounds a bit low to me. I normally use 3g or 6g per 1l (1/2 to 1 tsp per l). Can someone comment on treatment rates for mollies/tetras?

I used the same thing. It is actually the best to fix fungal infection or bad bacteria living inside your tank. And most importantly it's easy and SUPER DUPER CHEAP.

Turn the heat up to 28C and add some Tonic Salt grain into your water and do water change at least 20% each day for 5 days. You'll see the result instantly

I had 150-170 fry of Siamese fighter fry and the fin rot infected almost all of my Siamese fry in 3 days but luckily I tried Tonic Salt, Oh man I glad I did. I managed to save about 100 fry and they were healing in just 2 days. Sadly about 50 of my fry were too late to be saved. The fin rot became body rot and they died from drowning. :tears:

I believe mollies can withstand quite a bit of salt in the water. I had Siamese fry and I only use about 5-8 grains per 5L of water. Normally I think 1teaspoon of Tonic salt is best to go with 20L of water for tropical fish. But for molly case i'm not sure.

Do the math

Whitespot needs to be treated differently from Fungus.

Whitespot is a parasite, personally I would be treating with Wunder Tonic and up temp to 28-30, gravel vac after 3 days, by then the parasite will be falling off the fish and into your substrate so you need to vaccum them up.

Continue with gravel vac's for the next couple of days after the 3rd day, if need be, treat again just to be safe.

Yes whitespot is a parasite, but the free swimming protozoa are intolerant to salt (you can only kill the parasite while in the free swimming stage).

http://www.aquaticcommunity.com/disease/whitespot.php":3eeem0cp]salinity up to 5 ppt (parts per thousand) will kill nearly always kill the parasites, but may be too strong for salt intolerant fish. If you keep catfish or equally sensitive species, bring the salinity no higher than 2 ppt

My black mollie has healed extremely well and quickly. Salt works likes magic. I have a happy fish now.
